BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a net support rack assembly, and more particularly to a net support rack assembly which is assembled and folded easily and conveniently.

2. Description of the Related Art

A conventional net support rack is disclosed in U.S. Pat. No. 5,816,956, entitled “NET SUPPORT STRUCTURE”. However, the net is mounted on the frame by its four ends, so that the mounting structure between the net and the frame is weak. In addition, the main body has a greater length, so that it is easily bent and deformed during a long-term utilization.

SUMMARY OF THE INVENTION

The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional net support rack.

The primary objective of the present invention is to provide a net support rack assembly, wherein the snapping end of the elastic lock is snapped into and locked in the hooking groove of the net, so that the net is fully stretched and expanded on the two longitudinal tubes by the elastic force of the elastic lock.
